Feng shui house numbers, like all numbers in feng shui, carry significance. Numbers can enhance the characteristics of a space. Because feng shui deals with single digits only, the easiest way to determine your feng shui house number is to add the numbers together.
Let's say your address is '1257 Elm St' Simply add 1+2+5+7 = 15. Then add 1+6 (the numbers in 15) to get 6. Take that number and refer to the meanings below.
Or you can take this one step further and assign a number value to each letter in your street name, and add that as well. This is an even better indicator. Here the cipher for that:
A=1, B=2, C=3, D=4, E=5, F=6, G=7, H=8, I=9, J=1, K=2, L=3, M=4, N=5, O=6, P=7, Q=8, R=9, S=1, T=2, U=3, W=4, X=5, Y=6, Z=7.
Finishing the example above, the math would look like: 1+2+5 + 7 = 15, 1+5 = 6, then E (first letter of Elm) =5, L=3, and M=4. Add 6 (the number already derived) to your house name numbers: 6+5+3+4 = 18, 1+8 = 9. In this case your feng shui house number would be 9.
